Disclosed is a diagnostic testing device that may be used to detect one or more analytes in a sample. The device comprises a receptacle and a holder for a test strip. The test strip may be, for example, a lateral flow test strip. The device and holder permit analysis of a sample, wherein the device is substantially sealed during testing and detection of results. To use, the holder containing a test strip is inserted into the receptacle containing sample to be analyzed. Capillary flow along the test strip is initiated by contact of the sample with the distal end of the test strip. The receptacle is such that results of the assay may be detected visually or using standard instrumentation such as by measuring light absorption or reflectance.

L'invention concerne un dispositif de test diagnostique pouvant être utilisé pour détecter un ou plusieurs analytes dans un échantillon. Le dispositif est constitué d'un récipient et d'un support à bandelette réactive. La bandelette réactive peut être, par exemple, une bandelette réactive à flux latéral. Le dispositif et le support permettent d'analyser un échantillon en faisant en sorte que le dispositif reste sensiblement étanche durant le test et la détection des résultats. Pour utiliser le dispositif, on insère le support contenant une bandelette réactive dans le récipient contenant l'échantillon à analyser. Le flux capillaire sur la bandelette réactive est déclenché par la mise en contact de l'échantillon avec l'extrémité distale de la bandelette réactive. Le récipient permet de détecter les résultats du test à l'oeil nu par des méthodes standard telles que la mesure de l'absorption de la lumière ou de la réflectance.
